Abstract: PROBLEM TO BE SOLVED: To easily place a document at a regular position of a document platen by providing a positioning guide which moves between the specified guide position and the retreat position of the document platen according to the position of a document cover. SOLUTION: When the document cover(DF) 18 provided with an automatic document feeder mechanism is opened and moved to a non press-contact position, a gear 60a is rotated in the direction of an arrow E with the movement of the DF 18, a gear 60d is rotated in the direction of an arrow L, and a rack 62 is moved in the direction of an arrow N, then the positioning guide 50 is also moved in the direction of the arrow N.

Title: Reception wave phasing circuit
Inventor: IKEDA HIROSHI
IPC: G01N29/22
Filed: 1989-11-22
Abstract: PURPOSE:To obtain a desired dynamic range by composing a TGC circuit by dividing into a first TGC circuit which performs the variable control of a gain setting an echo signal with high amplitude from the shallow part of an organism as a target, and a second TGC circuit which performs the variable control of the gain with low amplitude at entire depth setting the echo signal from the deep part as a main target. CONSTITUTION:An ultrasonic wave signal is transmitted at the leading edge of a trigger signal for transmission where it changes from 0 to 1. When transmission is completed, each oscillator immediately receives an ultrasonic echo signal from the organism. The first TGC circuits A1-An perform the variable control of the gain only for the period of time t1 from the transmission when the echo signal with high amplitude arrives, and vary the gain from 0(dB) to GA(dB) according to a gain function fA(t). Also, the second TGC circuits B1-Bn perform the variable control of the gain extending over the period of time t2 from the transmission to the next transmission, and vary the gain from 0(dB) to GB(dB) according to a gain function fB(t). As a result, the integrated dynamic range of the first and second TGC circuits goes to GA+GB, then, the gain control of the echo signal can be performed within the range.

Abstract: PURPOSE:To offer a natural picture quality where a border between an area subject to color conversion and an area not subject thereto is not remarkable in a picture after color conversion by replacing a color of a designated hue into a color of other hue while brightness and saturation remain unchanged. CONSTITUTION:A color original fetched by a picture input device 1 is outputted as an input 3-primary color signal 7.

The discrimination device 2 receives the signals 7, 8, projects the signal 7 into a color difference space such as L*u*v* so as to discriminate whether the signal 7 has a hue designated by the signal 8 and outputs the result as a color converter control signal 9. A conversion color storage device 4 stores a hue to be outputted after conversion in advance and outputs the result as a converted color signal 10. The color converter 5 receives the signals 7, 10 and applies color conversion such that only the hue is converted in case of the color conversion to the signal 7 in response to the signal 9 while brightness and saturation remain unchanged and outputs the result as an output 3-primary color signal 11.
